PUMPING MECHANISM.

Application filed June 22,

My invention relates to pumping mechanisms, and particularly to displacement pumping mechanisms.

An object of my invention is to provide an improved displacement pumping mechanism. Another object oi' my invention is to provide an improved displacement pumping mechanism whose component elements are especially convenient to assemble and disassemble and which take up a materially les; over-all space so that it is, as a result, capable of being inserted in a well casing of smaller diameter. Other objects and disadvantages of my invention will hereinafter more fully appear.

In the accompanying drawings l have shown for purposes of illustration one torn whichmy invention may assume inpractice.

In these drawings,-

Fig. 1 is a diagrammatic view of one illustrative embodiment of my invention incorporated in a complete system.

Fig. 2 is a view, partially in elevation and partially in central vertical section, through one of the displacement tanks used as a unit il the system.

Fig. 3 is a transverse section on the line 3-3 of Fig. 2.

Fig. 4 is an enlarged detail sectional view of the bottom of the lowermost displacement tank.

In the illustrative embodiment oi my invention I have shown the same incorporated in a displacement pumping system in which a compressor 1 discharges by way of a pipe 2 to an automatically operating switch mechanism 3 which operates to alternately supply air to one or the other of lines 4 and 5, the mechanism 3 herein connecting` the line which is not being supplied with air to the suction side of the compressor through a line 6. It will be evident that the pipe 6 may be omitted and the iiuid vented direct to atmosphere, it desired. The lines 4 and 5 are adapted to supply pumping fluid to a series of displacement tanks arranged in series in a well which is shown at 7. The well is lined with a casing 8 and within it there are a plurality ot' serially arranged displacement tanks 9 of which three are shown herein, but of which an even number will be used .in practice, so that two equal series may be dad. The first and other odd numbered' ltanksD counting' from the top, connected 1923. Serial No. 647,090.

with the pipe line 4, while the second and other ev en numbered tanks will be connected with the pipe line 5 in such manner that the odd numbered tanks may be vented Vso that they may lill while the even numbered tanks are discharging and vice versa. The tanks are generally the same in construction with the exception of the bottom tank whose difference will be briefly described hereafter.

in Fig. 2 will be observed one of the tanks, say the top tank. This tank comprises a cylindrical body member 10 threaded at its opposite ends as at 11 and 12, the top end having threadedly engaged with the threaded portion 11 an end closureA member 18 which is traversed by three holes, one ot these, 14, being coaxial with the axis of the cylinder 10 and having portions of different diameters, being of smaller diameter at the side adjacent the interior of the tank and ot larger diameter thereabove. rlhreaded into the opening 15 which constitutes the smaller diameter portion of hole 14 is a pipe 16 eX- tending substantially to the bottom of the section 10 where it carries threadedly se-` cured thereto a valve cage member 17 whose bottom is closed by a perforated valve seat member' 18, which aiiiords a seat for a ball check valve 19. It ywill be noted that the valve cage member 17 is of such length that the lower end thereof and particularly the .i seat member 18 projects beyond the end o;p the cylinder member 10 in such manner that by removing the lower closure member ot the cylinder' member 10 (which will shortly be described) access may be had readily to the ball check valve and the seat thereot1 tor the purpose ot permitting cleaning thereof, etc. The upper, or larger diametered portion 21, of the opening 14, has threaded thereinto a pipe 22 which constitutes the connection between the tank and the bottom of the next adjacent higher tank, the connection between the member 22 and the tank next above being the same as the connection of the corresponding member 22 from the next lower tank with the bottom ot the tank shown in Fig. 2. The member 18 is traversed by a hole of uniform diameter 24 through which the pipe 5 extends without interruption to the tank next below. W5 'll he member 13 is linally traversed by a further hole 2G, the disposition and the diameter 0;'7 which are auch. that it overlaps and opens into a recess 27 ivhich is threadedfor the reception of the threads 11 at thev top of the member 10 and overlies and communicates with a port or opening 28 which is displaced laterally trom the recess 26 and which in connection with the opening 28 constitutes an opening extending completely through the full thickness of the member 13. lt will be noted that into the opening 2S there is threaded a pipe member 29 ivhich entends through an opening; not shown in the drawings but corresponding to the opening 2, in the top head, oitV the next lower tank. Into the top oit the opening 2G thereis threaded a closure member SOfwhichcarries aV pipe connectionl with thel line it rl'he lower end oi the displacement tank is constituted by a member 32 which has a bore 83 formed there-in and which isV threaded to receive the lowery end ot theA pipe section 10, it being noted as pointedY out above that,` When the member 32 is removed, free access may be had to the standing or check valve member 19 and its seat member: 1:8, the member 32 being recessed tor-a substantial distance to permit the valve casing 17 to project intoA it. The member 32 is traverscdby a threaded opening Si intoA which the pipe 22, (referred to above) is threaded. The member 32 is also traversed by tivo other holes, one of which is shown in Fig. 2 at 36, and through this hole the pipe portion 29 extends in passing to the second loiver` tank. The other opening (not shown) permits the pipe line 5 to pass through it on: its Way to the next lower tank.

`With regard to the bottom tank, it is of the same general construction asa-.ll the other tanks described except tor the fact that it comprises an additional check valve. The bottom` closure member ot the bottom tank is of built-up construction and is designated 40 and is threaded on to the pipe section 10 Which constitutes the body out the lowern'iost tank. The member 40' has threaded thereinto an annular valve guiding portion 4:1 having Wings 4t2 so arranged as to properly center a check valve dit the Wings having projections eta extendinginwardly at their top to prevent the valve moving too lar eti' its seat and the member il being bored with an opening through its bottom for the tull diameter ot the check valve 43. ri`h-readed into the bottom ot the member i() is a valve seat member #i5 providing a valve seat i6 with which the valve i3 is adapted to cooperate, this member being screwed home into close contact with the bottom ot' the member al. As a result it will be evident that the valve will be smoothly guided and yet prevented by the members t1 and a5 from possiblyv escaping from its position.

|The general mode of operation of" this systemv Will be readily understood. rflic bottom tank will lill with liquid due to the head of Water in the Well and this charge will he progressively pumped up through the various higher chambers, it being understood. ot course, that the entire set oi chambers, hoivever, are working at the same time, halt et them beingV filling and halt ot them emptying. By reason of the arrangement ot the parts going to make up the dis alaccnieut chambers it will be clear that a tank ot maximum volume may be used and that the entire set el:` displacement chambers or tanks may be accurately centered in the casing 8, it being further apparent that, without any awkward projections or anything ot that variety the air supply lines. are adequately protected troml possible damage in inserti-ng and withdrawing the parts of the pumping system tor the Well and the whole system is secured together. Oi. particular advantage is the avoidance of any but vertical joints. i

While l have in this application specilically described one Ytorni Which my invention may assume in practice. it Will be understood that this term ot the same is shown for purposes et illustration and that the invention may be modilied and embodied in other forms Without departing fromy its spirit or the scope of the appended claims.
